Powders flow control valve (Twin rotor)

Summary

I realize the high-precision beginning to talk of every powders while being a compact powders flow regulating valve.

Principle

I arrange the opening department that powders pass in the tread of two adjacent rotors.
I change the effective cross section of the opening department and control quantity of beginning to cut of powders continually by turning this rotor in the contradicting direction.

Movie

The variable valve appearance

Variable valve internal structure

Rotor illustration

A cross section is variable with "the core variableness" from fully opening to fully closing it from fully opening by a twin rotor smoothly.

Characteristic

Not the intermittent beginning to cut such as the conventional rotary valve, I can perform more stable pneumatic transportation with a wide range continually.
It is available for abrasion characteristics and adherent strong powders.
Abundant saizubarieshon (50A - 100A)
Control is possible with range ability of normal 1-5 times.
